Naruto

"Kill THE bad guy."

This differs from

"Kill A bad guy."

Naruto and Inuyasha have one enemy and only one enemy. Orochimaru / Naraku. They never die. EVER. The main character's only goal is to kill that one person for whatever reason. The whole world hates that one person and the main character thinks he can get strong enough to kill him.

Naruto failed already when three of the strongest people in the world failed to kill the guy. Even a 2v1 when the baddie couldn't even use abilities. Sad.

Inuyasha ended already and Naraku is still alive. What.

Now, let's take other examples. DragonBall Z. Grr Vegeta is evil. K I defeated him. Grr Frieza is evil. K I defeated him. Grr Cell is evil. K I defeated him. Grr Buu is evil. K I defeated him.

Bleach. Grr Hollows are evil. K I defeated them. Grr Soul Society is evil. K I "defeated" them. Grr Aizen is evil. Well, we'll see what happens if it ever gets out of filler.

One Piece. Grr Alvida / Morgan / Buggy / Kuro / Krieg / Arlong / Smoker / etc. are evil. K I defeated them.

One Piece does not have the character who takes all the blame for being the ultimate evilest person in the world. DBZ does not have one. Bleach doesn't, but it might go that route. Inuyasha and Naruto do. That's why I hate them.
